Application filed September 22, 1926, Serial No.11365999, and in Canada April 19, 1927.

v- 'This invention relates to a fire extinguisher. l x ,A l

An obiect ot thelnvention is to provide a Vsimple and effective lire extinguisher adapted to spraypowder over a flame, The various features ot novelty and invention will apv pear trom the detailed description taken inv i Connection with the accompanying Sheet of Y V'42--2 of the Fig 1- drawings forming part of this application.

`Anembodiment 'ofqthe invention is illustrated inthe drawings, in which` l Fig. 1 is a longitudinal` sectional View through the extinguisher; f

Fig, 2 is a top yplan view taken on line Fig. 3 is a detailed sectional viewvtaken on line 3-8 of Fig. 1; and .L

Fig. 4 is a detailed sectional view taken on line4-4ot Fig. 11.- .p y l In the drawings, 1 indicates a container adapted to hold the powder to bey sprayed, and 2 a cap on the bottomV thereof for closing the opening through which the powder is inserted into the container. A cylinder 3 extends into the container and has a piston 4 arranged therein. This piston 4 is preferably formed ont cup leather and' is backed by a circular plate 5. The vpiston is mounted on an operating rod 6 being held thereon loetween nuts 7 and S threadedly arranged upon the said rod. A spring 9 is arranged within the piston 4 so that one end is attached to the operating rod 6, while the major portion of the spring bears against the inner circumference of the piston. This arrangement is clearly shown in Fig. 3 of the drawing. As

the cup leather piston 4 is apt to yshrink andv contract during non-use, the spring insures constant engagement between the said piston and the container 3, thusL providing at all times an eiiicient airtight piston within the cylinder. i Y Y The cylinder 3 projects a short distance beyond the upper end of the container 1, such projecting end being provided with exterior screw threads 10. An interiorly threaded cap 11is adapted to close the upperend of thecylinder. The cylinder is connected to they container' atV the point where the former projects through the latter byany suitable connecting means suchas bywelding or sol-` dering. The operating rod 6 passes through' a centrally formed opening in the cap 11. f A n I s holding means by this eye member; ,y l

he inner end et the cylinder 3 has an open the containerl being secured thereto in any'L suitable manner as indicated at 14. The funnel shaped member is e-orrugatedas shown in Fig. 4, such corrugations servingV tospace lthemembers12 and 13 so .asl toallow the powder to pass between the same.- The funnel shaped member 13 is providedy with a ta' pered seat 15 adapted to form' ay seat for a closure member 16 secured to the en d of theY .operating rod 6, This cl-osure member 16 may be threadedly attached to the said rod,

or it maybe attached in any desired manner.

A coil springl is `arranged upon the operating rod 6 between the closure member 16 and the nut 8. This spring tends to prevent the closure member 16 from contracting or relaxing from long non-use and allow the powder to escape.

The operating rod 6 is provided with a pair ot projecting lugs18 and 19, said lugs extending from the rod in lopposite directions.V These lugs are adapted to Y pass through oppositely extending slots 20 and 21 in the cap -11. 1t will thus be seen that when the extinguisher is not being used the operating rod 6 is turned soA that the lugs 18 and. 19 will pass through the openings 2O and 21 inthe cap; after which a slight turning movementof the rod will cause the same to remain in Vsuch position and the closure 16 to be firmly seated against the seat 15.

Suitable openings 28 in the sides of the" i tunnel arek provided for the purpose of providing a passage for the powder;

An operating handle 22 is threadedly at tached to the upper end of the rod 6. This handle has a downwardly projecting base portion 23 which is provided with a'hollow tubular part 24.V A 'coil spring 25 is ar` ranged upon the Vrod 6 within the hollow part 24l of the base. said spring bearing From the :foregoing description it will be ziplmrentvthat the tire extinguisher described therein will not deteriorate from nonnse :is
